I believe that most people are born with the ability to be good, kind and loving but that external things get in the way and cause perple to lose sight of whats really important.
Like a job, it becomes more important to get ahead and get promoted than it does to keep ones integerty. Keeping up with the Jones becomes more important than kindness. Being the thinnest or the most attactive, ect, these things distract us and it becomes easier to do the wrong things to get these distractions than it is to do the right thing.
I don't belive that most things are evil, wrong yes but driven by evil, no.
